Question

在我的c＃应用程序中，我想要窗体的窗口句柄。我知道＆＃34; .exe＆＃34;窗口的名称，所以我试过＆＃34; GetProcessesByName＆＃34;功能。我得到了应用程序的句柄，但不知道如何获取它的子窗口。指导我

Process[] p = System.Diagnostics.Process.GetProcessesByName("MyProcess");

foreach (Process p1 in p)
{
    MessageBox.Show(GetWindowText(p1.MainWindowHandle));
}

使用句柄p1，我需要获取p1的子窗口句柄。怎么做？

我使用“ GetProcessesByName ”等功能来获取主窗口的句柄和“ EnumChildWindows ”以获取子窗口的句柄。对于源代码，

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Windows.Interop;
using Microsoft.Win32;

[DllImport("user32.Dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool EnumChildWindows(IntPtr parentHandle,     Win32Callback callback, IntPtr lParam);

Process[] p = System.Diagnostics.Process.GetProcessesByName("StikyNot"); //this is for sticky notes
foreach (Process p1 in p)
        {                
            IntPtr MainWindowHandle = p1.MainWindowHandle;              

            List<IntPtr> GetChildWindowsHandle=GetChildWindows(MainWindowHandle);
        }

 public static List<IntPtr> GetChildWindows(IntPtr parent)
    {
        List<IntPtr> result = new List<IntPtr>();
        GCHandle listHandle = GCHandle.Alloc(result);
        try
        {
            Win32Callback childProc = new Win32Callback(EnumWindow);
            EnumChildWindows(parent, childProc, GCHandle.ToIntPtr(listHandle));
        }
        finally
        {
            if (listHandle.IsAllocated)
                listHandle.Free();
        }
        return result;
    }
